In 1979, the Yankees appeared eager to replicate the success of the Phillie Phanatic, the green, pot-bellied mascot that Mr. Harrison and Ms. Erickson created in 1978. In his first two years of existence, according to Mr. Harrison, Phanatic-related products generated $2 million in revenue—and his popularity has not waned.

He made more than 550 public appearances last year, has his own merchandise store in Philadelphia and is on display at the Baseball Hall of Fame.

Dandy, on the other hand, got thrown in a dumpster.

He was designed by Ms. Erickson, who had worked on “The Muppet Show” and created Miss Piggy, among other characters. Dandy was marketed as a “dyed-in-the-wool” Yankees fan.

He was blessed with a pear-shaped physique that was almost Ruth-ian. He had a hat that spun, a cartoon-size baseball bat and a big, bushy mustache that evoked Thurman Munson, the team’s star catcher—which was no coincidence.

Above all, Dandy was a New Yorker.

“He was supposed to be sassy,” Mr. Harrison said. “He was supposed to have that Yankee swagger.”

Nah, no mascots. No cheerleaders, no mascots. We’ve got enough nuts and clowns in the Bronx as it is.
